        Oppenheimer’s brief advance into astrophysics began with a 1938 paper about neutron stars, which continued in a 1939 installment that further incorporated the principles of Einstein’s general theory of relativity. He then published a third paper on black holes on September 1st, 1939—but at the time, it was scarcely noticed because this was the very day Germany invaded Poland, launching World War II. Oppenheimer never wrote on the topic again.
        Even if it hadn’t been overshadowed by war, Oppenheimer’s work on neutron stars and black holes “was not understood to be terribly significant at the time,” says Cathryn Carson, a historian of science at the University of California, Berkeley.
        Each paper was written with a different member of the swarm of graduate students that Oppenheimer carefully cultivated. These protégés facilitated his ability to jump between research topics—and ultimately, helped him develop some of his most important contributions to physics.
        Oppenheimer’s climactic third paper, written with his student Hartland Snyder, explores the implications of general relativity on the universe’s most massive stars. Although the physicists needed to include some assumptions to simplify the question, they determined that a large enough star would gravitationally collapse indefinitely—and within a finite amount of time, meaning that the objects we now know as black holes could exist.

Google Adds a Safeguard on Privacy for Searchers
By MIGUEL HELFT

        SAN FRANCISCO, March 14 — Web search companies collect records of the searches that people conduct, a fact that has long generated …16… among privacy advocates and some Internet users that valuable personal data could be misused.
        Now Google is taking a step to ease those concerns. The company keeps logs of all searches, along with digital identifiers linking them to specific computers and Internet browsers. It said on Wednesday that it would start to make those logs anonymous after 18 to 24 months, making it much harder to connect search records to a person. Under current practices, the company keeps the logs intact indefinitely.
        “We have decided to make this change with feedback from privacy advocates, regulators worldwide and, of course, from our users,” said Nicole Wong, Google’s deputy general counsel.
        But it is unclear whether the change will have its intended effect. Privacy advocates reacted with a mix of praise and dismay to it.
        “This is really the first time we have seen them make a decision to try and work out the conflict between wanting to be pro-privacy and collecting all the world’s information,” said Ari Schwartz, deputy director of the Center for Democracy and Technology, an advocacy group. “They are not going to keep a profile on you indefinitely.”
        Others were less enthusiastic. “I think it is an absolute disaster for online privacy,” said Marc Rotenberg, executive director of the Electronic Privacy Information Center.
        Ms. Wong said Google uses the search data internally only to improve its search engine and other services. She added that Google would release search data only if compelled by a subpoena. Even so, Google was the only major search engine to resist a Justice Department subpoena for vast amounts of search data last year — a move that drew praise from privacy advocates.
        Just how personally revealing such data can be became evident last year, when AOL released records of the searches conducted by 657,000 Americans for the benefit of researchers. …17… AOL did not identify the people behind the searches, reporters from The New York Times were able to track down some of them quickly through their search requests.
        The ensuing flap caused AOL to tighten its privacy policies. The company now keeps search histories for only 13 months and does not link them to Internet protocol addresses — digital tags that can identify a specific computer.
        For its part, Yahoo keeps search data for “as long as it is useful,” said a spokeswoman, Nissa Anklesaria. And Microsoft said that while it does not keep search histories alongside I.P. addresses, it can connect the two if law enforcement requests it.

The Amazon Forest


The Amazon is often called the lungs of the earth and produces 20% of the world’s oxygen. For this reason, many people are trying to stop deforestation in the rainforest. Brazil, for example, is working hard to help the rainforest survive.


A few years ago, the Brazilian government put forward a plan called ARPA (Amazon Region Protected Areas). It had the support of many international agencies, including the World Bank, and the German Development Bank, KfW. The main aim was to build new areas of protected rainforest, maintain areas of the rainforest that hadn’t yet been destroyed, and stop deforestation. Deforestation contributes greatly to global warming because carbon dioxide is released into the atmosphere when trees get cut down and burned.


One of the first areas to be recognized as part of ARPA was the Tumucumaque Mountains National Park. It is 38,800 km2 and is the same size as Switzerland, a small country in Central Europe. It’s the world’s largest protected tropical national park, and the second largest national park. It is home to certain species of jaguar, eagle, and lizard, which can only survive in the rainforest. Many of these species are under threat from climate change and deforestation.


In order to work in the park, conservationists need a reliable map. However, no map existed, and they didn’t have enough knowledge to make one on their own. They came up with the idea of involving local tribes to help them, combining modern and ancient methods to produce a map. The tribes learned to use global positioning system handsets (GPS), in conjunction with their local knowledge of the area, which included fishing and hunting grounds, and places of historical or mythical importance. Aerial photos were a 20useful aid in the process as well. This method of map-making is now the key to the future of rainforests, in Brazil and the rest of the world too.
